They disappeared from most of the Northern Hemisphere as the climate cooled: The last of the adapiforms died out at the end of the Miocene (~7 mya). [43] The fossil record suggests that the strepsirrhine adapiforms and the haplorhine omomyiforms had been evolving independently before the early Eocene, although their most basal members share enough dental similarities to suggest that they diverged during the Paleocene (66–55 mya).
[80] Yet some or all of the brown lemurs (Eulemur) are cathemeral, which means that they may be active during the day or night, depending on factors such as temperature and predation. [116], Extant strepsirrhines have an epitheliochorial placenta,[50] where the maternal blood does not come in direct contact with the fetal chorion like it does in the hemochorial placenta of haplorhines.

The omomyids are another extinct group of prosmians but they are believed to be haplorhines, closely related to the tarsiers, but an outgroup to the rest of the haplorhines. [129] Like other primates, strepsirrhines are relatively slow breeders compared to other mammals. All Lemuriforms have a toothcomb. Lemurs rafted from Africa to Madagascar between 47 and 54 mya, whereas the lorises split from the African galagos around 40 mya and later colonized Asia. The suborder Strepsirrhini is composed of seven families split into three groups. Sharp cusps on the teeth of some of the smaller adapiforms, such as Anchomomys and Donrussellia, indicate that they were either partly or primarily insectivorous.

[8], When British zoologist Reginald Innes Pocock revived Strepsirrhini and defined Haplorhini in 1918, he omitted the second[9] "r" from both ("Strepsirhini" and "Haplorhini" instead of "Strepsirrhini" and "Haplorrhini"),[10][11] although he did not remove the second "r" from Platyrrhini or Catarrhini, both of which were also named by É. Geoffroy in 1812. [34][49] Originally, adapiforms were all included under the family Adapidae, which was divided into two or three subfamilies: Adapinae, Notharctinae, and sometimes Sivaladapinae. None have been seen to hunt or to eat a significant amount of non-insect meat. Lemuriform primates may have evolved from either cercamoniines or sivaladapids, both of which were adapiforms that may have originated in Asia. [62] Further genetic evidence for the relationship between tarsiers and simians as a haplorhine clade is the shared possession of three SINE markers.
Both their place of origin and the group from which they emerged are uncertain.

However, significant evidence suggests that Cheirogaleidae is not related to the lorises, and that Indridae is sister-group to Lemuridae. †AdapiformesLemuriformes[a] (See text) Their brain's olfactory lobes are larger, lending to the notion that they have a stronger reliance on smell. [134], Among extant strepsirrhines, only the diurnal and cathemeral lemurs have evolved to live in multi-male/multi-female groups, comparable to most living simians. Locomotion:Many lorisiformes are slow quadrupeds, like this slow loris. The lemurs of Madagascar, living in the absence of simians, are more variable in their activity cycles. This video shows a mouse lemur scampering on all fours across the tree-branches, as well as jumping from branch to branch. [72] Although the authors noted that Darwinius was not a "fossil lemur", they did emphasize the absence of a toothcomb,[73] which adapiforms did not possess. [106][117] Extant strepsirrhines also have a lower basal metabolic rate, which elevates in females during gestation, putting greater demands on the mother. Strepsirhine skulls have: A medium-sized, rounded brain case; Relatively large eye sockets; A forwardly directed orbit for binocular vision - the orbit is relatively larger in nocturnal species than diurnal species; These newer finds demonstrate that lemuriform primates were present during the middle Eocene in Afro-Arabia and that the lemuriform lineage and all other strepsirrhine taxa had diverged before then. [105][108], The strepsirrhine rhinarium can collect relatively non-volatile, fluid-based chemicals (traditionally categorized as pheromones) and transmit them to the vomeronasal organ (VNO),[109] which is located below and in front of the nasal cavity, above the mouth.

[112] The VNO is connected to the mouth through nasopalatine ducts (which communicate via the incisive foramen), which pass through the hard palate at the top, front of the mouth. [83] It is used to comb the fur during oral grooming. Often, the toothcomb is incorrectly used to characterize all strepsirrhines. The first group is the infraorder Lemuriformes, four families of creatures typically called lemurs.

[e] Both appeared suddenly in the fossil record without transitional forms to indicate ancestry,[31] and both groups were rich in diversity and were widespread throughout the Eocene. Strepsirrhini or Strepsirhini (/ ˌ s t r ɛ p s ə ˈ r aɪ n i / (); STREP-sə-RY-nee) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. [7] In his description, he mentioned "Les narines terminales et sinueuses" ("Nostrils terminal and winding"). The aye-aye, mouse lemurs, woolly lemurs, and sportive lemurs are nocturnal, while ring-tailed lemurs and most of their kin, sifakas, and indri are diurnal. [6] Confusion of this specific terminology with the general term "strepsirrhine", along with oversimplified anatomical comparisons and vague phylogenetic inferences, can lead to misconceptions about primate phylogeny and misunderstandings about primates from the Eocene, as seen with the media coverage of Darwinius. Distribution:Lemuriformes are only found on Madagascar and the Comoro Islands, where they face no competition from more advanced primates, like the ones living on the mainland of Africa. The Strepsirrhini is a suborder of primates comprised of the adapiforms (which are already extinct) and the lemuriform primates (such as lemurs, lorises, pottos, and galagos).

[50] In Africa, the lorises and galagos diverged during the Eocene, approximately 40 mya. Diet:Since lemuriformes adapted to a variety of different niches on Madagascar, they eat a variety of different foods. [91][144], The now extinct adapiform primates were primarily found across North America, Asia, and Europe, with a few species in Africa.

Much of their habitat has been converted for human use, such as agriculture and pasture. Lemuriens. Strepsirrhini (lemurs, lorises, and other primitive primates) Primate taxonomy reflects the evolutionary relationship between different groups of primate species. [32], Lemuriform origins are unclear and debated. International Union for Conservation of Nature, "Lemurs found to be 'most threatened mammals' in the world", "Chapter 5: The phylogenesis of human personality: Identifying the precursors of cooperation, altruism, and well-being", "Giant rabbits, marmosets, and British comedies: Etymology of lemur names, part 1", "Chapter 19: Human universals and primate symplesiomorphies: Establishing the lemur baseline", "Complete primate skeleton from the Middle Eocene of Messel in Germany: Morphology and paleobiology", "Suite au tableau des quadrumanes. [86] Both living and extinct strepsirrhines lack a thin wall of bone behind the eye, referred to as postorbital closure, which is only seen in haplorhine primates. [63], Because of their historically mixed assemblages which included tarsiers and close relatives of primates, both Prosimii and Strepsirrhini have been considered wastebasket taxa for "lower primates".

They disappeared from most of the Northern Hemisphere as the climate cooled: The last of the adapiforms died out at the end of the Miocene (~7 mya). [43] The fossil record suggests that the strepsirrhine adapiforms and the haplorhine omomyiforms had been evolving independently before the early Eocene, although their most basal members share enough dental similarities to suggest that they diverged during the Paleocene (66–55 mya).
